Five things I know about style: Erdem

1) I made very decided style choices from the age of six. I was an odd child. I'd become obsessed with a colour and only wear that for as long as possible. For a year I only wore blue. 2) I'm a uniform dresser. I wear the same thing consistently because I'm a creature of habit. I'd describe my style now as preppy and unco-ordinated. I love wearing my glasses because they stop me from bumping into things, and I wear a lot of corduroy. My new Aran sweater is my favourite piece at the moment. 3) Looking completely like yourself and effortless is what makes a person stylish. Wearing things that don't go together – making beautiful mistakes – can really work. 4) I like to treasure old things. My dad had a large collection of 60s and 70s ties which he's given me. I wear them all the time, and I love the fact that they were his. 5) A great pair of shoes takes you far. They make you feel good, and they're a confidence booster. It's the first thing people look at usually – one's eyes start from the bottom and work upwards.
